Fig. 21

a shows the visualization characteristics of the Top quark decay at the LHC and b shows the visualization characteristics of the lightest SUSY particles (LSPs), the Neutralinos and the Charginos, as depicted by the subtle purple and orange dots, respectively. The Neutralinos and the Charginos signal events as depicted in b needs to be extracted from the background Top quark decay events using the BDT Multivariate Analysis (MVA) technique.
